Carta is a proprietary platform for managing cap tables, equity, and 409A valuations, widely used by startups to track ownership and run funding rounds. It's the default choice for many companies, but pricing is per-stakeholder with minimum annual fees, and your equity and investor data lives on Carta's platform.
Malak is the open-source alternative to consider if what you actually need is a lighter investor-relations hub — sharing KPIs and fundraising updates with investors — rather than Carta's full compliance-grade cap table and 409A machinery.
